The 42-year-old singer was all set to head off on a reunion tour with her ex-bandmates – Tina Barrett, Paul Cattermole, Jon Lee, Bradley McIntosh, Jo O’Meara and Rachel Stevens – until the death of Cattermole aged 46 in April.
Shortly after his death, it was announced Hannah – who was in a relationship with Cattermole for five years in the noughties – would not be joining the fellow Reach For The Stars hitmakers on their 2024 tour after all.
With their history, it was suspected Hannah left the band due to grief, but in December she opened up about an autoimmune health battle she’s been dealing with for the past few years, rendering her unable to even cook at one point.
Now that the mum-of-two is set to appear on Dancing on Ice on January 14 she’s further detailed her health struggles and talked of her decision to leave S Club 7 on today’s episode of Loose Women.
‘S Club 7 unfortunately will never, ever be the same again and it just unfortunately wasn’t the right time for me to continue,’ she told the ITV panel of Nadia Sawalha, Christine Lampard, Katie Piper, and Joanna Page.
‘Is doing Dancing On Ice a sort of part of that, to get well physically, mentally?’ Nadia asked.
‘Yeah. I mean I didn’t know that I was going to be doing it at that time, and, yeah, my health was sort of…’ Hannah replied, trailing off.
‘It was struggling a bit with different symptoms and I went to see this doctor who actually put me onto this new treatment.’
She continued: ‘I went to see him and the treatment was working really well. But then, my body was ready for exercise and I was like, “Okay, what can we do?”
‘It’s been great for anxiety because you have to focus. I can’t be thinking about my phone or anything,’ she added.
Activist and presenter Katie asked Hannah where she gets her strength from, to which the Bring It All Back hitmaker replied: ‘My family. You keep going.’
Going into detail about her health condition, Hannah added that her energy levels were ‘so so low’ and she wasn’t the best she could be.
Last month, Hannah chatted candidly in an interview with Hello! Magazine, in which she described having chronic fatigue, brain fog, and vertigo.
She first experienced symptoms in 2013 after having breast implants, and she and her husband Adam Thomas believe the condition was triggered by two miscarriages in 2022 and stress.
She told the publication: ‘I don’t think I realised how much I’d deteriorated because it happened so gradually, I had no energy and couldn’t even get on a train or cook dinner.
‘That affected my mental health, too, because I’ve always been a physical and sporty person, it’s only when you get better and can do things you love again that you realise how bad things were.’
Back in October, Hannah spoke to The Sun about her reasons for leaving the band.
‘I was extremely excited – we all were – to get back as a seven. But then Paul died and everything changed. It gave me time to reflect on whether it was the right thing for me to do,’ she said.
Cattermole and Hannah dated from 2001 until they called it quits in 2006, three years after the band split.
They rekindled their romance during a 2015 reunion but eventually parted ways again.
Hannah now has two children – Tea, four, and Tora, three – with husband Adam Thomas.
